The body’s internal clock not only determines when we sleep, but also how quickly our muscles heal. A new study of mice by Northwestern Medicine, published in Science Advances, suggests that muscle injuries heal faster when they occur during the body’s natural waking hours. The findings could have implications for shift workers and also prove […]
Blue Light: The Health Benefits and Risks
Blue-enriched light can improve the sleep quality and daytime activity of older adults living at home, according to a new study from the University of Surrey. Researchers found that this type of light therapy led to more daytime activity, earlier bedtimes, more regular sleep patterns and improved sleep quality, offering a promising non-pharmacological approach to […]
Cellular Aging in One Organ Can Lead to Multiple Organ Failure
The aging and malfunctioning of cells that occurs when one part of the body is damaged can spread to other organs, a study has found. Scientists have shown for the first time that cell damage in a damaged liver can trigger a process associated with aging and dysfunction, and then spread to otherwise healthy organs […]
New High-Resolution 3D Maps Show How the Brain’s Blood Vessels Change With Age
Healthy blood vessels are not only important for heart health. Vascular well-being is critical for brain health and potentially for combating age-related cognitive decline and neurodegenerative diseases such as Alzheimer’s disease, according to a new study led by Penn State researchers. The findings point to a previously understudied but potentially crucial role that the brain’s […]
Sleep Apnea Can Impair Memory
Poor sleep quality can have a negative impact on memory. Research has already shown that fluctuations in nightly sleep duration and reduced sleep quality impair older adults’ ability to recall information about past events. It has been known for decades that important things happen during sleep in terms of consolidating memory and strengthening recollections. Current […]
